The Safest and Toughest Cycle Helmet - As seen on Dragons Den. 


Enkayse is the result of extensive research, testing and development. A proprietary material developed and owned between Hedkayse and their scientific partner company.

Head injury is serious, so are Hedkayse.

A cycle helmets performance is measured through it’s ability to dramatically reduce the transfer of impact energy to the head and brain in the event of an accident. This is set through specifically engineered testing standards. All cycle helmets must conform to these standards legally (In Europe this test is called EN-1078). However, the test does not allow for the risk of daily use and smaller impacts. To avoid this, cycle helmet manufacturers state you have to replace your helmet even after the smallest of knocks.

 With Hedkayse, you don’t .

Unlike EPS Enkayse is designed to manage the energy of impacts whilst retaining its integrity. Enkayse dissipates energy rather than deforming on impact, it also cushions small bumps. Protection from small knocks and bumps may also have long-term benefits as researchers believe the cumulative effect of small knocks contributes to brain disease over time.

Enkayse shrugs off the bumps, knocks and everyday abuse, so you can be sure that Hedkayse | ONE will provide continuous protection.

How to Fit


Before placing the helmet on your head, ensure the rear 'whale tail' is enclosed by the two rear side pieces, and the rear 'hook-and-loop' strap is threaded through the second black plastic 'k-clip'.


Ensure the branded 'Enkayse" X-shaped piece is centred at the base of the helmet.

Tighten the rear 'hook-and-loop' strap until the helmet feels snug but not constricting. Making sure the strap is securely fastened to itself


When adjusted, the side buckle should sit below your ear but above the jawline, with the two webbing straps forming a ‘T’ as shown. 


The helmet should sit 1-2 centimetres above your eyebrows - not so far forwards that it obscures your vision, and not too far backward that it exposes any more of your forehead.

Insert the ratchet part of the clip into the main clip component, you will hear and feel it click several times into a secure location. To release the clip, pull down on the red tab attached to the chin ratchet.


A comfortable fit should be tight but will also allow you to get three fingers between the clip and your neck without feeling discomfort.


All loose ends (4 ends total) can be secured using the rubber rings. For an extra secure fit, tuck/fold the webbing ends back towards themselves to make the webbing 3 layers thick and then secure tightly with the rings.
